VENT ILATING WATER-CLOSETS.

Application filed June 9, 1923.

To all whom it may concern.-

Be it known that EDWARD H. RAPER and CHARLES E. Barns, citizens of the United States, residing, respectively, at Mapleton in the county of Monona and State of Iowa, and Sheridan, in the county of Sheridan and State of Wyoming, have invented new and useful Improvements in Ventilating lVater-Closets, of which the following is a specification.

This invention relates to water closzts, and more particularly to a toilet ventilating device for removing the noxious gases from the bowl while the latter is in use.

One of the essential features of our invention consists in the provision of means whereby foul odors are prevented from escaping into the room, and are conducted through a tube having inclined openings therein, whereby they combine with a jet of water and are drawn through a siphoning trap tothe waste outlet.

A further object of the invention resides in providing means for normally maintaining the overflow pipe closedso that the air passing through the ventilating chamber is taken entirely from the toilet bowl, and the possibility of any air escaping from the overflow to the chamber when the latter isin use is eliminated.

Referring to the drawings wherein is set forth the preferred embodiment of our invention,

Figurel is a side elevational view of a toilet bowl with our invention attached thereto, showing parts in section.

Figure2 is a sectional view taken substantially along the line 22 of Figure 1.

Figure 3 is a sectional view taken sub stantially along the line'83 of Figure 1.

Figure 4 is a sectional view taken substantially along the line 4-4 of Figure 1.

Figure 5 is an enlarged detail sectional view of the spraynozzle and the ventilating tube:

Figure 6 is a rear end view partly in section, showing a slightly modified form lip 11 and the waste pipe 12, which has an angularly bent arm 12' that conducts the waste from the bowl to any suitable outlet.

Serial No. 644,38 1.

The bowl 10 is formed with the usual flushlng rim 13 having circumferentially spaced perforations lel,which receive the water from the flushing tank 15 through the pipe 16. The pipe 16 at its upper end terinmates in an offset overflow 17, which is normally closed by means of a cork plug 18, having depending spring fingers 19, extending down into the pipe, which permit the cork to raise when the overflow is needed, and guides the cork back to its normal position when the overflow is cut off.

A ventilating chamber 20 preferably positioned to one side of the bowl comlimited distance within the tube 22, the tube being preferably curved at its upper end as at 29 to snugly receive the nipple 27 so as'to insure the proper positioning of the tube 22 in the casing. Obviously, the chamberQO may communicate directly with the bowl 10 instead of through the perforations ll in the flushing rim, so as to receive' the noxious gas in said bowl.

The nozzle 26 is preferably secured to-the chamber 20 by means of an internally threaded recess 30 formed in the upper por tion of the nozzle, which isadapted'to engage a correspondingly externally threaded portion 31 in the chamber 20.

The supply pipe 32, which leads to the flushing tank 15 'is'provided with a branch pipe 33 having preferably a manually controlled "valve 34 positioned adjacent the seat of the bowlso as to regulate the supply to the nozzle 26.

A siphoning trap 35, as shown in Figure 4, communicates with. the ventilating chamber 20 through an opening 36, and is divided by the'partition37: in'to'the compartments 38 and 39, which are connected to each other by the orifice 40 adjacent the upper end of the partition. Under the siphonic action of the trap, the contents of the ventilating chamber passes through the openings 36 and 40 and deliver to the compartment 38, from where it passes through a spillway or opening 41 in the bottom of the compartment 38 to the horizontal portion 12 of the outlet 12 and mixes with the waste from the bowl 10 before being led to the soil pipe through the opening 42. The perforations 23 terminate at the flange 24 so that the lower portion of the tube 22 is closed thus allowing air to be conducted from the chamber 2O into the tube only from that portion of the tube above the flange 24.

In order that the air emptied into the bottom of the chamber 20 through the tube may be prevented from escaping upward, a partition 25 is arranged to extend across the interior of the chamber 20 as shown in Figure 4. The liquid inthe ventilating chamber 20 and thetrap 35 is prevented from freezing by reason of the removable drain plug 43, which preferably engages an opening formed in the bottom of the chamber 20.

The nozzle 26 may be provided with a removable plug 44, which will permit the admission of any suitable solution into the nozzle so as to prevent the return of sewer gases through the ventilating chamber when the toilet is not in use for a long period of time.

In order to operate the ventilating device, it will be seen that it is merely necessary to turn the handle 34, conveniently positioned adjacent the seat, which will cause a jet of water to be admitted into the nozzle 26, from where it passes through the opening 28 down the perforated tube 22, and combines with the foul air coming from the bowl through the openings 14 and passage 21 to the chamber 20, the foul air being drawn into the tube 22 through the inclined openings 23 due to the suction created by the downward movement of the water from the nozzle 26. The water and airbeing combined together in the chamber 20 are delivered through the openings 86 and 40 to the compartment 38, where they are led through the spillway 41 to the arm 12 of the waste outlet 12, and carried by the opening 42 to the soil pipe.

It will be noted that by reason of the closure cap 18 on the-overflow 17, the only air that is permitted to enter the ventilating chamber is that which comes from the bowl 10, and that the tube 22 maybe readily removed from the interior of the chaihber20 when the nozzle 26 is disengaged from the upper portion of the chamber.

The modified form of the invention shown in Figure 6 is substantially similar to that previously set forth, with the exception that the ventilating chamber 45 is positioned closer to the bowl so that the water coming from the nozzle 46 is conducted, together with the air entering the tube 47, through the opening 48 into the trap and down the passageway 49 through the opening 50, into the waste 51, where they are carried through the orifice 52 to any suitable outlet. It will be noted that in this compact form of the invention, the communicating passages are connected by round corners so as to reduce to a minimum the resistance of the water being conducted through the chamber and trap to the outlet.

It is to be understood that the form of the invention herein disclosed is merely illustrative, and in no sense restrictive, and that such changes as fall within the purview of a mechanic may be made without departing from the spirit of the invention and the scope of the appended claims.
